> maybe I am even in a privileged position financially; but at this moment in my life I would rather quit my job
Someone closer to retirement with a lot of savings and low expenses will have a completely different answer than a younger person with low savings and a family.
The second variable it depends on is their current salary. Someone who currently earns a huge number can afford to give up a higher percentage than someone who earns barely enough to make ends meet.
The question becomes a proxy for the person's financial situation and current salary, not their remote work preferences.
This is also a question where people's claims don't match their actions. Similar to every election season when a lot of people declare they're going to move to a different country if their party loses, but the number of people who actually do it is much smaller.
